Technical Overview of DGMX2-5-PP-AW-E-S-30 Vickers Hydraulic Valve
I. Product Overview
This valve is astackable pressure-reducing valvefrom Eaton Vickers' SystemStak™ series, primarily used in hydraulic systems tomaintain stable outlet pressureand prevent overpressure in actuators under reaction loads. The model code denotes:
• DGMX2: Series identifier (stackable pressure-reducing valve)
• 5: Nominal diameter (5mm)
• PP: Pressure adjustment method (manual knob with locknut)
• AW: Valve body material (cast iron with rust-proof treatment)
• E: Seal type (enhanced seal)
• S: Installation method (stackable, supports multi-station manifolds)
• 30: Design sequence (specific pressure rating and flow characteristics)

III. Structural Features
1. Design Advantages:
• Two-stage spool design: Dynamically compensates for inlet pressure fluctuations to ensure stable outlet pressure.
• Multi-station compatibility: Supports manifold installation, simplifying hydraulic system layout.
• Modular design: Can be stacked with other SystemStak™ valves to achieve complex function combinations.
2. Critical Components:
• Pressure Adjustment Mechanism: Provides three adjustment methods (knob, nut, micrometer).
• Sealing System: Enhanced seals (high-temperature and wear-resistant).
• Installation Interface: ISO 4401 standard compliant, supports flanged, threaded, or SAE interfaces.
IV. Application Areas
• Construction machinery: Pressure control in hydraulic circuits of excavators and cranes.
• Agricultural machinery: Hydraulic system integration in tractors and harvesters.
• Metallurgical equipment: Hydrauli c transmission systems in rolling mills and presses.
• Special applications: Hydrauli c systems requiring explosion-proof certification (specific certification levels need to be confirmed).
V. Installation and Maintenance
1. Installation Guidelines:
• Stacking Order: It is recommended to place the pressure-reducing valve in the middle of the manifold, close to the actuator.
• Torque Requirements: Refer to the screw specification table (e.g., M6 bolt torque is approximately 8-10 N·m).
2. Maintenance Recommendations:
• Regular Calibration: Check the pressure setting every 1000 hours. Adjust if the deviation exceeds 5%.
• Troubleshooting: If the outlet pressure is unstable, prioritize inspecting the spool wear and seal condition.
